A little murder-for-hire plot apparently couldn’t kill the romance between lawyer Sanford Asher and Swiss miss Line Grosjean – he’s been shopping for a sumptuous love nest where they can live happily ever after.

“Just last week, he was looking at places that she might like,” a real-estate source told The Post.

Grosjean pleaded guilty this week to conspiring to have Asher’s estranged wife Jayne killed, and was packed off to Rikers Island for six months.

But even though the 20-year-old former stripper planned to frame Asher, 56, for the never-carried-out slaying and trashed the deep-pocketed sugar daddy to investigators, he’s stood by her.

Asher, who left his wife after a steamy encounter with Grosjean at the nudie Paradise Club in midtown, paid for her defense lawyer and even got special permission for a 15-minute reunion with his jailed lover before she entered her guilty plea.

The source said Asher was still looking for pricey digs after Grosjean’s arrest.

But there’s no guarantee Grosjean will set up house with him. Because she has pleaded guilty to a felony, she faces possible deportation back to Switzerland when she’s sprung from jail.
